Say 'cheese'! At $30, Crest's teeth-whitening kit is down to its Prime Day price

'Tis the season for sangria, spritzes and cherry slushies, which means your teeth might be looking a little dingier than you'd like. The easiest way to refresh and brighten your smile could be a trip to the dentist for a pricy bleaching treatment, or you can opt for at-home Crest 3D Whitestrips. Scoop up these smile-brightening favorites for just $30 (down from $46). That's as low as it was for Prime Day!

Why is it a good deal? 💰

If you're someone who keeps an eye out for sales on teeth whiteners, you know they're hardly ever discounted this much — the kit is 35% off! So now's the time to buy: It's hard to beat a respected brand like Crest when it comes to at-home whitening, and $30 is nothing compared to what you'd spend on an in-office whitening treatment. This price matches the lowest we've seen so far this year.

Why do I need this? 🤔

The pack includes 22 treatments, with one upper and one lower strip for each session. With improved sealing technology, these strips no longer slip, so you can drink water — even talk — while using them. Just peel off a strip, apply it to your teeth and leave it for 30 to 45 minutes. You'll start to notice a whiter smile in as little as three days, with the full effect in about 20 days. You'll also get two treatments' worth of 1-Hour Express strips to use on days when you want speedy, same-day brightness.

What reviewers say 💬

More than 74,000 Amazon shoppers give this teeth whitening kit a glowing five-star rating.

Pros 👍

"They actually work, y'all!" exclaimed one shopper. "I can hardly believe my own eyes! I'm sold! I just saved $250 for professional teeth bleaching."

"So many came in this that literally two or three people could use them with noticeable difference, or even just to brighten your teeth up a bit every now and then," wrote another gleeful grinner. "It feels impossible to finish! I’ve definitely been able to bypass crazy teeth staining from implementing turmeric in my cooking, which I’ve avoided due to the staining!"

"Once I confirmed that my dentist approves [of] this kit, I had to buy it and try it," shared a third fan. "I'll be 50 next month, and I've grown up in the South, so I had too many years of tea staining my teeth. I can tell a huge difference after using these."

Cons 👎

"Does as advertised, but makes my teeth a little sensitive," noted one buyer. "I had to wait between treatments for sensitivity to die down."

"I was going to wait until I was fully done with the treatment to do my review, but wow!" exclaimed a generally pleased purchaser. "I'm only on day five, and the difference is already visibly noticeable. ... I didn't even realize just how yellow my teeth truly were until I saw this difference, whew. Only complaint is they sometimes come up on the sides, and I feel like that makes them lose their effectiveness on my further-back teeth."
